Early in the 2026 NFL season, undefeated records for the Kansas City Chiefs, Buffalo Bills, Las Vegas Raiders, Minnesota Vikings, and San Francisco 49ers have positioned those clubs as frontrunners for division titles and playoff berths, while teams like the Cleveland Browns, Jacksonville Jaguars, Baltimore Ravens, and Denver Broncos hold strong positions in the wild-card race after Week 3. Recent results, including strong defensive showings and point differentials, have elevated some bubble squads while winless starts for the Miami Dolphins, Los Angeles Chargers, Houston Texans, and Tennessee Titans have dimmed their postseason prospects. Upcoming Week 4 matchups, such as Chiefs-Raiders and several NFC North and East contests, along with injury reports, rest advantages, and divisional tiebreakers, will further shape the seven-team playoff fields in each conference.
